Thank for kind words, but please do not advertise at random projects on itch io, it takes away people from main topic and there are better sites to advertise your pixelart. It looks cool, but is clearly too expensive for me.
Maybe you could try your luck on Fiverr? I don't have money, but on Fiverr you will easily find right people that will be interested in your work as freelancer and will be more than willing to pay for your work.
